Flipper Zero hardware & wireless hacking tool gets an app “store” with open-source app

Flipper Zero portable multi-tool for pentesters and hardware hackers has now gotten an app “store” with currently around 100 free and open-source apps available through the device’s Android or iOS app. I missed it at the time, but the Flipper Zero launched on Kickstarter in July 2020 and was massively popular with close to 5 million dollars raised from almost 38,000 backers. The tool looks like a toy but it allows hacking with GPIOs and short-range wireless protocols such as Bluetooth, RFID, NFC, and infrared. Flipper Zero specifications: Wireless MCU – STMicro STM32WB55RG with Arm Cortex-M4 application core @ 64 MHz, Arm Cortex-M0+ network core @ 32 MHz, 1024 KB flash, 256KB SRAM Storage – MicroSD card slot up to 64GB Display – 1.4-inch monochrome LCD (black on orange background) with 128×64 resolution via ST7565R SPI display controller Connectivity Bluetooth 5 LE & 802.15.4 via STM32WB55 microcontroller Bluetooth LE – […]

Yahboom DOFBOT 6 DoF AI Vision robotic arm for Jetson Nano sells for $289 and up

Robotic arms can be expensive especially if you want one with AI Vision support, but Yahboom DOFBOT robotic arm designed for NVIDIA Jetson Nano offers a lower cost alternative as the 6 DoF robot arm sells for about $289 with a VGA camera, or $481 with the Jetson Nano SBC included. We previously published a review of the myCobot 280 Pi robotic arm from Elephant Robotics, and while it’s working well, supports computer vision through the Raspberry Pi, and is nicely packaged, it sells for around $800 and up depending on the accessories, and one reader complained the “price tag is still way too high for exploration“. The DOFBOT robotic arm is looking more like a DIY build, but its price may make it more suitable for education and hobbyists. DOFBOT robotic arm main components and specifications: SBC – NVIDIA Jetson Nano B01 developer kit recommended, but Raspberry Pi, Arduino, […]

ESP32-S3 based Arduino Nano ESP32 board supports Arduino and MicroPython programming

The Arduino Nano ESP32 is an ESP32-S3-based WiFi and Bluetooth microcontroller board designed for IoT applications for hobbyists and enterprise use cases. The new Nano board comes with 8 MB PSRAM and 16 MB flash storage and can be programmed with either the Arduino or MicroPython languages. It’s not the first ESP32 board from Arduino, as the Nano RP2040 Connect pairs a Raspberry Pi RP2040 MCU with an ESP32 module from u-Blox and the just-released Arduino UNO R4 WiFi marries a Renesas RA4M1 Arm Cortex-M33 MCU with an ESP32-S3-MINI-1 module. But the Arduino Nano ESP32 is different since it’s the first ESP32 board from Arduino where the Espressif chip is the only microcontroller onboard and handles both wireless connectivity and GPIOs. Arduino Nano ESP32 specifications: Wireless module – u-Blox NORA-W106-10B with MCU – ESP32-S3 dual-core Xtensa LX7 microcontroller @ up to 240 MHz with vector extensions, 512KB SRAM, 384KB ROM, […]

The Bee Data Logger ESP32-S3 board comes with RTC, microSD slot, and two Qwiic connectors for sensors

A few months ago, SparkFun released the “Datalogger IoT – 9DoF” no-code platform based on ESP32 with some built-in sensors, a microSD card, and two Qwiic connectors to add sensors in order to perform data logging with minimal to no coding. Smart Bee Designs looks to have shrunk the design, removing the built-in sensors in the processor, with the Bee data logger ESP32-S3 board that offers most of the same features plus a built-in DS3231 RTC and back battery for timekeeping, and the ability to leverage the vector extension in the ESP32-S3 for machine learning applications. Bee data logger specifications: Wireless module – Espressif Systems ESP32-S3-MINI-1 module CPU – ESP32-S3 dual-core Xtensa LX7 microcontroller with vector extensions with 512KB SRAM, 384KB ROM, WiFi 4 and Bluetooth 5.0 connectivity Storage – 8MB of QSPI flash PCB antenna Storage – MicroSD card slot up to 16GB capacity USB – 1x USB Type-C port […]

Diabolic Drive is a penetration testing USB key with 64GB storage, ESP8266 and ATmega32U4 microcontrollers

Diabolic Drive may look like a 64GB USB flash drive and show as such when you insert it into your computer, but it’s actually a wireless keystroke injection tool with a Microchip ATmega32U4 8-bit AVR microcontroller and an Espressif Systems ESP8266 WiFi SoC. Egypt-based UNIT 72784 says their cyber security tool enables Red Teaming – the practice of rigorously identifying an attack path to breach a device’s security – as it behaves like a flash drive while being able to deploy keyboard strokes wirelessly through the ESP8266 WiFi MCU. Diabolic Drive specifications: MCUs Microchip ATmega32U4 microcontroller @ 16 MHz (5V) acting as a Serial Bridge Espressif Systems ESP8266EX microcontroller @ 160 MHZ (3.3V) with WiFi 4 support ATmega32U4 and ESP8266 are connected via Serial and I2C protocols thanks to an LDO regulator. Storage 64 GB flash storage up to 20MB/s read, 10MB/s write 4MB W25Q32 SPI flash memory o Antenna […]

An ESP32-S3 board for vending machines with RS485, microSD card slot, optional cellular mPCIe module

LILYGO T-Vending is an ESP32-S3 WiFi and Bluetooth IoT board designed for vending machines with an RS485 terminal block, a microSD card slot, and support for an optional cellular mPCIe module. As I understand the board is connected to the vending machine through the RS485 terminal block to control vend motors (potentially via an additional board to control multiple motors) and a 10-pin connector for power (12V/24V), signals to/from a coin mechanism and other parts. The board also adds a Grove connector and an unpopulated 12-pin GPIO header for expansion. T-Vending specifications: ESP32-S3-WROOM-1 wireless module SoC – ESP32-S3FN16R8 dual-core Tensilica LX7 microcontroller @ up to 240 MHz with 2.4 GHz 802.11n WiFi 4 and Bluetooth 5.0 LE connectivity Memory – 8MB PSRAM Storage – 16MB SPI flash PCB antenna Storage – MicroSD card slot Wireless 2.4 GHz 802.11n WiFi 4 and Bluetooth 5.0 LE connectivity (ESP32-S3) Optional T-PCIe 4G LTE […]

ESP32-S3 board features 2.8-inch display, Blackberry-like keyboard, and optional LoRaWAN connectivity

LILYGO T-Deck is a development kit with an ESP32-S3 WiFi and BLE module, a 2.8-inch display with touchscreen support, a Blackberry-like keyboard based on ESP32-S3, and optional LoRaWAN connectivity through an SX1262 LoRa module. It looks ideal for text-based messaging, but the devkit also includes two microphones and a speaker so audio communication must be possible. Other features include a MicroSD card slot, a Grove connector (UART) for expansion, and support for a LiPo battery with USB charging. LILYGO T-Deck specifications: ESP32-S3-WROOM-1 wireless module SoC – ESP32-S3FN16R8 dual-core Tensilica LX7 microcontroller @ up to 240 MHz with 2.4 GHz 802.11n WiFi 4 and Bluetooth 5.0 LE connectivity Memory – 8MB PSRAM Storage – 16MB SPI flash PCB antenna Storage – MicroSD card slot Display – 2.8-inch IPS display with 320×240 resolution; ST7789 SPI display controller Audio – Built-in speaker using MAX98357A amplifier, 2x MEMS microphones Wireless 2.4 GHz 802.11n WiFi […]
